With 11 confirmed reports of wrong-way drivers on the Dallas North Tollway this year and four cases involving fatalities in 2009, the North Texas Tollway Authority made multiple changes on its toll roads in the past year.

They include placing LED-enhanced signs on selected exits, software that alerts the command center to wrong-way movement on exit ramps and mainlanes, reflective tape on sign posts and raised pavement markers.

NTTA is working with Dallas on initiating median improvements on Wycliff Avenue between Dallas’ North Tollway and Maple with proposed modifications designed to reduce the chances of an accidental left turn from eastbound Wycliff to the southbound DNT.

The NTTA has completed plans, specifications and estimates and is currently coordinating pre-bid activities with a November 2011 completion goal.
